Getting NA when I run a standard deviation

0 votes
a quick query I read the variable data from my csv file. There is a column with the label "var" that contains numbers.

I execute the command

sd(data$var)
I get

Instead of my standard deviation, [1] NA.

Could you please tell me what I am doing incorrectly?
